STAPLE-BINDING DELIVERY MECHANISM FOR PRINTING-MACHINES.

SPECIFICATION formingpart of Letters Patent No. 615,2 59, dated December 6, 1898. Application filed December 31, 1897. Serial No. 665,171. (No model.

To all whom, it may concern:

Be it known that I, LUTHER O. CRoWELL, a citizen of the United States, residing at New York, (Brooklyn,) county of Kings, and State of New York, have invented certain new and useful Improvements in Staple-Binding Delivery Mechanism for Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The present improvements relate in a general sense to that class of stapling mechanism especially adapted for attachment to a webprinting machine to form a part of the delivery mechanism therefor, whereby the plicated material in the form of webs or sheets may be bound together in packs by meansof staples set therein during the onward progress of the plicated packs, and thus form a completed product, such as a pamphlet or newspaper g hose leaves are bound together in book-like More specifically my invention includes a holder adapted to grip the staple upon a setting-bed after the same has been formed and presented to the bed, and means for operating the holder to bring it to and retract it from its setting position.

My invention further consists in certain features and details of construction, which will be hereinafter described, andpointed out in the claims.

In the drawings annexed hereto and forming a part of this specification, Figure 1 is a front elevation of the delivery of a printingpress embodying my invention, some of the parts being broken away. Fig. 2 is a side elevation of the same, the point of View being indicated by the arrow 2 in Fig. 1. Fig. 3 is a section, on an enlarged scale, showing parts of the mechanism on the line 3 3 of Fig. 2. Fig. l'is asection, on an enlarged scale, on the line 4 4 of Fig. 3, the point of view being to the left of the line. Fig. 5 is a plan, on a larger scale, of the stapling mechanism, the point ofview being indicated by the arrow 5 in Fig. 3; and Figs. 6, 7, and S are sectional views, similar to Fig. 3, showing different positions of the parts, Fig. 6 showing the staple as nearly formed, Fig. 7 showing the formed staple placed upon the setting-bed and gripped there by the holding device or swinging jaw, and Fig. 8 showing the staple as being clenched, the holding device undergoing retaction.

Referring to the drawings, the web or webs of paper a are led to the stapling mechanism from any appropriate printing and folding or associating mechanism between the carriers A B, which support the stapling mechanism and which may also carry cutting and fold-. ing mechanism, although of course, if preferred, the cutting and folding operations may be. performed by other means. The paper may be presented to the stapling mechanism in the form of webs or of sheets. The particular form of such mechanism herein. shown, but to which I do not in any way limit "myself, is the longitudinal web-folder of my Patent No. 331,280, of which and are the nipping or folding rollers.

The staples in connection with which my present invention is to be used may be formed outside of the machine and merely set in the material by the machine, or they may be formed in the machine itself as well as set.

The machine shown herein is of the character which both forms and sets the staples. The mechanism shown is also one in which the staples are set with their legs in a line transverse to the run of the fabric being stapled. It will, however, of course be understood that the invention may be applied to a machine in which the staples are set with their legs in range with said line of movement.

In the machine herein shown, as usual in machines of like character, several separate stapling mechanisms are arranged side by side upon the carrier B. As these mechanisms. are precisely alike, it will be understood that the description herein applies to each of them, although the parts are referred to for convenience as in the singular rather than in the plural number.

The wire forming the staples is led from the spool 1 between thev feeding-rollers 2 3, which rollers are moved from the Worm-wheel 4, and thus passes under the fixed anvil 5 and in front of abutment 6 in manner'similar to that described in my Patent No. 510,840 and substantially identical with the manner described in my pending application, Serial No. 566,347, filed October 21, 1895. The wire is then severed by a knife of the usual construction (not shown) and is formed by being swept along the eccentrically-curved face of the anvil 5 by the bender or former 7, which is reciprocated in a recess in the carrier by an arm 8, mounted on the rock-shaft 9, provided with a rock-arm 10, operated by a fixed cam 11. Before leaving the anvil the legs of the staple are given a converging inclination by the plates 12 12', as described in my said application, and are then deposited by the retiring bender upon the setting-bed 13, preferablyat a point 14, where a groove is adapted to receive them and hold them during the op eration of setting. The staple formed in this or any other manner having been placed upon the setting-bed, the device which constitutes my present invention now comes into action to hold the staple in position while it is penetrating the material.

It is obviously necessary that the stapleformer 7 should be retracted into its socket when it reaches the point at which the two carriers are nearest in contact, and to prevent interference with the material it is desirable that this movement should not be caused by direct impact with the surface of the opposite carrier, but that the former should be positively withdrawn before such impact is possible. This withdrawal must be so made if contact between the staple-former and the material being stapled is to be avoided as to leave the staple inadequately supported. My present invention consists of means for holding the staple in theposition in which its legs may be forced through the material, which means are of such a character and so operated as not to come in contact with the material being stapled. The form of my invention shown in this application, to which, however, I do not limit myself, is that of a swinging jaw 15, mounted on short shaft 16, bolted to the framework of the cylinder between the legs of the bender 7. This jaw is rocked on its shaft by an arm 17, mounted upon a rock shaft 18, which is provided with a rock-arm 20, carrying a bowl, which is controlled by the overhanging cam 21, fixed to the frame. (See Fig. 2.) This cam is so shaped that as soon as the staple is deposited upon the setting-bed by the retiring staple-former the swinging jaw advances to the position shown in Fig. 7. Its lip passes over the crown of the staple and holds it in the groove in the settingbed until the legs of the staple have penetrated the material being stapled, and the staple is therefore held in position by the material when the swinging jaw is withdrawn, as appears in Fig. 8, and the clenching of the legs of the staple follows by means of a clenching-die 22, which may be either movable or stationary, and in this case is shown as mounted upon the carrier B. The lip of the jaw 15, which engages the staple, is preferably fiat and of about the width of the staple-crown,

so that it effectually prevents buckling of the crown while the staple is being driven.
